1.5.15. If the hammer is to be operated at low temperature or after long storage, allow the hammer to operate
for few minutes without load, for its internal elements get properly lubricated.
Do not use three jaw drill chuck when the hammer drill is set to hammer drilling or chiselling mode. This chuck
is designed only for regular drilling in wood or steel.
Failure of the considered instructions may lead to electric shock, fire and / or severe injuries.
2. Functional description and purpose of the hammer drill.
Hammer drill is a hand-operated power tool with insulation class II. The tool is driven by single-phase
commutator motor. Hammer drill can be used for drilling holes in working mode with hammer, digging channels, or
surface processing of materials such as concrete, stone, brick etc. Range of use covers repair and building works,
and any work from the range of individual, amateur-enthusiast DIY activities. Not permitted the use of power tools
for activities other than its intended purpose.
3. Information on noise and vibration emitted.
The values are measured according to EN 60745. A level of noise generated is generally: the sound pressure
level Lp
A
= 95,1 dB (A); sound power Lw
A
= 108 dB (A). Uncertainty K = 3 dB. Work with a silencer! The resultant
value of vibration (the vector sum of the three directions) is determined according to EN 60745: Drilling in metal: the
value of the emitted vibrations a
h
= 4,7 m/s
2
, uncertainty K = 1,5 m/s
2
, hammer drilling in concrete: value the emitted
vibrations a
h
= 19.402 m/s
2
, uncertainty K = 2,0 m/s
2
.
That in this operating manual for the vibration value is measured by the method specified in EN 60745 and
can be used to compare different power. The level of vibration varies depending on the specific activity carried out
and in some cases may exceed that amount in that direction. If power is used for a long time in this mode, the load
caused by vibration, could be underestimated. Directions: For an exact estimate of the burden of vibrations in a
working cycle should be recorded and the intervals in which the power is off or idling. This can significantly reduce
the reporting burden of vibrations throughout the business cycle.
4. Preparing for the job. Installation of accessories and auxiliary tools.
4.1. Auxiliary handle.
Use only the hammer drill fitted with an auxiliary handle . There is a special thumb (pos.9) that loosens the
handle ring around the machine.
4.2. Placing the drill in the chuck. Turn off the power of hammer drill. For hammer drilling and chiselling, SDS-
plus tools are required that are inserted in the SDS-plus drill chuck.
The SDS-plus drill chuck allows for simple and convenient changing of drilling tools without the use of additional
tools.
Insert the SDS-plus quick. Clean and lightly grease the shank end of the tool. Insert the tool in a twisting manner
into the tool holder until it latches itself. Check the latching by pulling the tool. As a requirement of the system, the
SDS-plus drilling tool can move freely. This causes a certain radial run-out at no-load, which has no effect on the
accuracy of the drill hole, as the drill bit centres itself upon drilling.
The dust protection cap (7) largely prevents the entry of drilling dust into the tool holder during operation. When
inserting the tool, take care that the dust protection cap (7) is not damaged.
4.3. Removing SDS-plus drilling tools. Push back the locking sleeve and remove the tool.
5. Inclusion and exclusion. Beware of the voltage of supply network! Supply voltage of the network must conform
to the details shown on the plate of power. Appliances marked with 230 V, can be supplied with a voltage of 220
V.
5.1. To start the machine, press the On/Off switch
5.2. To switch off the machine, release the On/Off switch
5.3. Hammer drilling.
Press the release button and place the switch (3) the symbol “hammer drilling.” Switch (3) falls in the
correct position with a distinct twinge.
Long lasting drilling at low rotational speed of the spindle may cause motor overheating. Make periodic breaks
in operation. Do not cover holes for motor ventilation in the hammer drill body.
